Thirty-five millimeters is probably my favorite focal length, but I didn't know it until I tried this lens on film. It's not too wide, but wide, and offers a fairly undistorted image. This lens was one of the first in my collection, and as such, has some external imperfections, if you will. The wide open performance isn't all that hot, but I don't think this is an issue with my lens but is a characteristic of this model in general. This aperture of f/2 is the fastest 35mm Pentax has at this focal length, unless you are able to find the theoretical f/1.4 version which appears on their roster but none have ever seen.
The lens is 205 g (0.45#) and, focused at infinity, 42mm long (1.6 inches) and has 6 aperture blades and 49mm filter threads. The fast aperture of f/2 is faster than average for lenses of this focal length. The lens bears the usual aperture ring and has a rubberized grip for easy manual focusing. Minimum focus distance is 30cm (11.8 inches) producing 1:6.25 reproduction ratio (0.16x).
